SPARK TOY.

Application file'd May 16, 1927, Serial No. 191,788, and in tireat'n ritajn October 18, .1928.

This invention relates to a toy and it is distinguished from known models in that, by a spring-controlled rack a toothed-wheelgear-mechanism is operated and a spark producing device arranged above the casing is rapidly rotated, the brushes of sparks produced by the spark-producing device being broken in star-shapes and becoming visible through a glass-pane which covers the spark producing mechanism. In

the brushes of sparks produced by the sparkapertures n producing mechanism appear at alternating intervals and in different colours, a

,disk having apertures and transparent'elements of different colours is loosely mounted on the shaft of the spark-producing mechanism above the glass-pane. The result of this arrangement is that, by the rotation of the spark-producing mechanism, the disk having colouredtransparent elements is re tat-ed at reduced speed from the shaft of the spark-producing mechanism. The sparkbi'ushes produced by the spark producing mechanism are visible through the slowly rotating transparent elements of this disk in different colours and arrangements.

An embodiment of the invention is shown, by way of example, in the accompanying drawing in which Fig. 1 is aside elevation partly in section.

Fig. 2 is a top plan view. Y

In slots of a casing w a rack b is ided which meshes with a pinion d keye vertical shaft 0 andmade in one piece with a spur-wheel f. The vertical shaft 0 is shift ably mounted in slots of the casing a. g a By a pressure exerted upon the outer end of rack 71 the shaft 0, and with the same the pinion dand spur-wheel f is shifted in the slots of the casing, thepinion being rapidly rotated owing to its engagement' with the rack, so that the spurwheel 7, when it comes in gear with the pinion g, communicates a rapid rotating movement to this pinion g and to the shaft h of the same. The rack b, when released, is returned into the initial position by the action of a spiral-spring 11 attached at the one end to the casing and at the other end to said rack. In the 'casinga one-element of a spark-producing mechanism, for instance an emery disk In, is mounted fixed on the casing 01, the other element, i. e. a cerium stone Z, being fixed to a disk m, adapted to be rotated by shaft h'.. This disk m has different through which the brushes of order to make on'a sparksproduced by the friction of the cerium stone Z-on the emery-disk k can pass. On shaft hi a head 0 is fixed over which a disk p 1s placed which has several apertures'q closed by sheets 0 of'transparent material coloured in different colours.

When the toy is being operated this upper disk 3? 1s rotated by the action of the centrifufal force, so that the spark brushes become visible successively through the transparent elements 1' in slowly changing colours.

ring 8 on head 0 serves to secure disk 1) in its position.

The operation is as follows By a pressure exerted upon the outer. end of rack b the spur-wheel f is brought into en gagement with the pinion g' which, together with shaft h and the emery disk 70 and disk m, is rapidly rotated. The disk ;0 with the transparent elements '1- is much more slowly rotated by virtue of the frictional contact with rotating shaft it, upon which it is loosely mounted. Brushes of sparks are produced by the cerium-stone sliding along the emerydisk 70, said sparks passing through the apertures n of disk m, so that they light the transparent elements 1'. A continuously changing coloured picture is thus produced as the disk m with the cerium-stone rotates rapidly while disk 1) with the transparent elements rrotates slowly;
